A communication apparatus includes a storage unit that stores service information corresponding to a service which can be read by another communication apparatus by a first wireless communication method, a communication unit that communicates with the other communication apparatus by a second wireless communication method, and an acquiring unit that acquires from the other communication apparatus, which read the service information from the storage unit, a message indicating whether a service corresponding to the service information is executable. A determination unit determines, based on the message, whether to start execution of the service with the other communication apparatus, and a detection unit detects that reading of the storage unit is performed by the other communication apparatus. The determination unit determines whether to start execution of the service based on the acquired message after it is detected that reading of the storage unit is performed.
